My vehicle is displaying a hybrid system check message, and the hybrid system malfunctions. This is causing the vehicle to stall in drive while the vehicle is in motion. The vehicle loses all capabilities to properly function. I was on a city street when this happened, and had to coast the vehicle downhill in traffic to pull over. My engine check light also illuminated. This vehicle has not been driven regularly, as I just purchased it from a dealership that had been sitting on it for some time. The carfax check out for the vehicle, so it could be a faulty electrical system inverter.

The leather on the dashboard breaks off in pieces. Can't attach anything to it, such as cell phone holder. Leather on dashboard just tears right off.

2006 Lexus Rx400H totally shutting down while I was driving on I4 today. No power steering, no power brakes, engine died and luckily I was able to coast to a safe place from 70mph! right before it happened, the check engine light came on, the engine misfired, then all of the lights on the dashboard came on including the check vcs, check hybrid and check anti-lock. Had to have it towed to our mechanic because it wouldn't start and could not be driven onto the tow truck. Codes that it threw said it was a high voltage system regenerative malfunction and a bad engine coil. It was a very dangerous situation with it shutting down on the interstate and I had no control what so ever! this was the second time this happened to me in this car and the computer was replaced the week after I purchased this car used in October 2017.

The hybrid system light turned on. Next were the brake and ABS lights turned on, then the was stalled in the middle of the road. The car was in motion and I was able to steered it to the side of the road. It was on the street road. I checked for the recalls related to the VIN, but no recalls for this vehicle although there were 6 recalls total. One of the recall related to the inverter coolant. It happened to me twice once at around 120K and now 135,828 miles.my VIN is [xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The vehicle dash has developed premature cracks, and is shining and sticky. Lexus claims this is only a cosmetic issue however the dash is an integral part of the vehicle and with the dash deteriorating the foam padding is harding creating a safety issue in event of crash. Lexus has admitted to the issue however has only offer repairs to a limited arbitruary number of owners while arbitruarily excluding other owners. There should be a manatory recall on this issue as is a safety issue.

I purchased this car on 6/11/2016 with 125, 812 miles. I am now at 140, 949 and today while driving down the road with my daughter in the car my vsc maint light, ABS light, brake light, and track stabilizer light all came on at the same time. I have contacted the Lexus dealer in regards to campaign number 13V396000 as this recall identification is identical to what happened today. This being my only vehicle which carries myself and my child this seems to be a very dangerous issue. The dealership informed me that all of these recalls have been repaired and my vehicle is not covered. If this car was repaired it is obvious it was not repaired correctly, if at all. This repair would cost me close to what I paid for the car itself! I would like documentation that my vehicle has in fact been repaired as I am better off buying a different car and junking this one than paying to repair it.

Cracked dashboard issue (as per the so-called warranty issue per csc-10057809-9406). 10-months ago I was promised parts by Lexus of monterey, ca, and, I've since contacted them five or more times...no parts are forthcoming. The Lexus regional manager offers no help. What can I do?

RX 400h 6-cyl

  • 70,000 miles
The check engine light and P0aa6 warning illuminated and vehicle went completely dead, could not start up. There were cracked body seams above the rear door strut mounts allowing water intrusion to flood the entire bottom well under the floor boards which shorted out the entire hybrid battery system. There were no visible signs of water intrusion inside the cabin of the vehicle, nothing was wet. Apparently, Lexus has two tsb's on this issue, L-sb-0019-09 & L-sb-0045-09, on how to repair the seams since over time there appears to be a structural flaw allowing the seams to separate. The water intrusion happens silently and without warning and presents a severe safety hazard as you get water into an electrical system and parts begin shorting out without advanced warning. Imagine traveling at a high speed and the hybrid battery shorts and the vehicle abruptly stops! or an electrical short starts a fire! Lexus is aware of the potential problem and how costly the damage is and the safety risks associated as a result and has chosen not to issue a recall or limited campaign to allow for a simple repair of the seams to prevent major damage from occurring.
